For the Plasma 5, we took Ergonomic Design to a whole other level.
The position of the rider directly influences the force distribution during the pedal stroke and consequently determines pedaling efficiency while the position of the rider’s upper body directly affects aerodynamic drag. An aerodynamically positioned torso will lower drag therefore improve aerodynamic performance. Saddle and handlebar adjustability were in effect a major topic during the developmental phase. Considering the idea that this bike would be ridden by riders of all shapes and sizes, from World Tour riders to long-distance triathletes, the Plasma 5 offers a wide range of adjustability to follow suit.
2 Stem Options
For the Plasma 5 there are two stem options available: while the TT stem stays in line with the top tube and allows for a very low position on the bike the riser stem (Triathlon configuration) increases handlebar stack by 45mm while maintaining the reach of the TT stem and allows for the installation of the clip-on Aero Drink.
Plasma 5 Aeria Handlebar Concept
The novel handlebar concept features wide range adjustability, a high-degree of compatibility, allows for proper integration of cables and wires and incorporates the airfoil innovation of the Plasma 5.
There are three base bar options that feature different heights and widths and allow for a reach modification of up to 15mm:
-30mm drop/400mm width
+30mm rise/420mm width
The spacers allow for a height adjustment of up to 75mm for the arm rests and extensions. The trailing edge of the spacer features a removable cover that provides easy access to the internal channel where the electronic shifting cables are routed.
The extension clamping system features a Ø22.2mm (7/8”) clamping standard to maintain interchangeability with all available extensions from Profile Design and most other brands.
The new pad construction features a narrower mounting option and a lower pad design for improved aerodynamic performance and adjustability.
Seat Clamp Adjustability and Seat Post Offset
Compared to the Plasma 3, the seat post of the Plasma 5 is not in line with the seat tube but rather at an angle. The resulting saddle clamp adjustment range remains almost identical independent of saddle height. In addition, the seat post has been modified and features an additional 10mm of horizontal adjustment.
The F01-X230 parametric airfoil was specifically developed for the Plasma 5.
Long distance triathletes spend several hours on their bike before switching to the running segment. While aerodynamics and ergonomics are key factors for a fast and efficient bike split, nutrition and hydration are essential to maintain a high pace during both the bike and running legs.
Long distance triathletes spend several hours on their bike before switching to the running segment. While aerodynamics and ergonomics are key factors for a fast and efficient bike split, nutrition and hydration are essential to maintain a high pace during both the bike and running legs. With this in mind, the engineering team developed a sophisticated storage system that stands above the rest due to its high degree of usability, while not hampering the aerodynamics of the bike nor the ergonomics of the rider.
Plasma 5 Aero Drink
The aero drink features a clip-on connection that ensures a firm fixation to the stem and allows for installation and removal of the bottle in a matter of seconds. The hydration system offers a low-weight body made from dishwasher-safe material with a large filling opening. A smooth bottle-frame intersection lowers aerodynamic drag due to optimized airflow recirculation behind the bottle.
The storage box features a removable divider and sufficient space for up to 8 energy bars. The rubber top cap grants easy access while drain holes at the bottom of the box prevent water accumulation. The solid body shell ensures an optimized airflow while offering enough knee clearance for the rider. The standard 64mm assembly bolt mount ensures interchangeability with a standard bottle cage.
